Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to the use of hydrogen peroxide in disinfec-tion regimens and to a means for dissipating residual hydrogen peroxide which may be present on or absorbed in the treated substance or items after disin-fection is completed.  In particular, the invention provides for the treat-ment of any bacteria contaminated object or surface with hydrogen peroxide to effect sterilization and thereafter removing any hydrogen peroxide remain-ing with the treated item by contacting it with a sterile aqueous solution containing pyruvic acid or any water soluble salt thereof in an amount which is effective to react with and decompose the hydrogen peroxide.  The present invention represents a significant and unique departure from known methods in that it works well with plastic components such as soft contact lenses without any adverse deterioration of the lens.

Abstract: ABSTRACT           An in-line pattern forming apparatus includes a windowed endless roller conveyor disposed in a longitu-dinal system path for sequentially receiving sets of ar-ticles.  A friction shoe shifts the set of articles through the conveyor window to an underlying turntable which is rotatable for selectively reorienting the set, whereupon the lead roller at the end of the window pushes the set off the turntable to a staging support which sequentially receives a plurality of sets to form a pattern.  The pattern is then swept as a unit from the staging support to a con-tainer loader or other associated apparatus in the system path.  Means may be provided for selectively shifting sets of articles on the staging support laterally of the path to facilitate formation of certain patterns.

Abstract: ABSTRACT          FORMATION OF AMORPHOUS MATERIALS         Metastable amorphous or fine crystalline materials are formed by solid state reactions by diffusion of a metallic component into a solid compound or by diffusion of a gas into an intermetallic compound.  The invention can be practiced on layers of metals deposited on an amor-phous substrate or by intermixing powders with nucleat-ing seed granules.  All that is required is that the dif-fusion of the first component into the second component be much faster than the self-diffusion of the first com-ponent.  The method is practiced at a temperature below the temperature at which the amorphous phase transforms into one or more crystalline phases and near or below the temperature at which the ratio of the rate of diffu-sion of the first component to the rate of self-diffusion is at least 104.  This anomalous diffusion criteria is found in many binary, tertiary and higher ordered sys-tems of alloys and appears to be found in all alloy sys-tems that form amorphous materials by rapid quenching.          The method of the invention can totally convert much lar-ger dimensional materials to amorphous materials in prac-tical periods of several hours or less. .

Abstract: Abstract of the Disclosure HEAVY DUTY HOSE COUPLING AND METHOD FOR MANUFACTURE OF HOSE-COUPLING COMBINATION      The coupling (10) has a stem (31) and a ferrule (14). The stem (31) is placed against an uncured hand-built steel cable reinforced hose (12).  The steel reinforcement cable (20) is spiraled onto a smaller diameter portion of the stem (31).  The ferrule (14) is then slid over the stem (31) and over the reinforcing cable layers (20). Epoxy resin (27) is injected through ports in the ferrule to embed the reinforcing cables and securely fix the hose structure to the stem and ferrule of the coupling.  A cover (26) is applied over the ferrule.  The hose-coupling assembly is subjected to heat and pressure to cure the elastomeric portions of the hose and securely bond them to the surfaces of the coupling.  The hose-coupling assembly is useful in very heavy duty applications where the assembly must withstand large end load strains when the hose is not under internal pressure, such as hose for use on a jetting sled.

Abstract: ABSTRACT OF THE DISCLOSURE    In a cyclic VSA system for air fractionation by selective adsorption of nitrogen from the feed air during an on-stream adsorption period in said cycle in which period an oxygen-enriched primary effluent discharged from the adsorption column is collected in a surge vessel, the duration of the on stream adsorption step is automatically controlled by a sensing device monitoring inventory of gas collected in said surge vessel.  In an alternative embodiment the adsorbed nitrogen is withdrawn by vacuum desorption of the column and collected in a second surge vessel, from which second vessel a portion of the nitrogen is subsequently withdrawn for use in rinsing the nitrogen laden column, said second surge vessel being likewise equipped with inventory monitoring means operative for automatically controlling the extent of the rinsing step. Alternately, when nitrogen is collected in a second surge vessel, the system may be operated by inventory monitoring of both surge vessels or only one surge vessel wherein another technique is used to control the other surge vessel.

Abstract: ABSTRACT OF THE DISCLOSURE            A  piston is formed in two parts.   The main part is formed by  gravity die casting from aluminium or  aluminium  alloy and  a  second part of the piston is formed  by  a  squeeze casting process to produce a material which is stronger and more  resistant  than  the gravity die  cast  aluminium  or aluminium alloy.  At least one piston ring groove is formed in  the second part.  The two parts are then electron beam welded  together to form the complete piston.   The squeeze cast  portion may be reinforced with whiskers or  fibes  to further   improve   its   properties.    This   method   of construction  has the benefit that only the minimum  amount of  the  piston is formed by the more expensive  and  time-consuming  squeeze  casting  process so that parts  of  the piston  which do not require the improved properties  given by squeeze casting are simply gravity die cast.  This is of particular benefit in large diesel pistons.
